Letters Patent No. 70,117, dated October 22, 1867.

APPARATUS FOR BURNING HYDROGARBONS'.

TO WHOM IT MAY .CONCERN A Be it known that we, II. A. V. PosT and.Turrini GAnnAnn, both of Cincinnati, Hamilton county, Ohio, haveinvented a new and useful Method of Burning Oils; and we hereby declarethe following to bea full, clear, and exact description thereof,reference being-had to the accompanying drawing, making part of thisspecification.`

This invention relates to a method of burningpetroleu'm and other oils,which insure very thorough combustion, and consequently lessons thesmoke, and burns the fuel to best advantage, consuming a largeproportion' of the combustible matter with clear, hot fiame.

The essential feature of your invention consists in supplying all orpart of the air for combustion of the oil by blowing the said airthrough the body of the liquid into a eombustionsehamber. This chambermay be arranged immediately above the surface of the oil, and beneaththe boiler, or other object to be heated, and providedwith a smallchimney or exit-flue for the smoke.

These objects are accomplished by carrying on the combustion by forcingair, or air mingled with steam, throughthe body of the oil. This can beaccomplished by means of a blower, or ,by forming a. partial vacuuminside the furnace or smoke-stack, so as to draw or drive the air!ithrough the oil by the pressure of the atmosphere. To accomplish thispurpose we employ any mechanical arrangement'thtttwe deem applicable tothe particular object in view; for example, where generation of steam isdesired, the parts may be arranged as represented. The accompanyingdrawing shows by'ivcrtical section one arrangement by which this may bei performed.

A is a steam-boiler, B a furnace, and C an oil-receptacle. D is a steampipe, having a valve-cock, E, and

nozzle F. The said nozzle discharges into a combined steam and airpipe,j'G, and thence into the chamber I-I beneath the oil-receptacle,and from which it is separated by a perforated oorfI, whose aperturesmay be provided witlrnozzles z' for more effective distribution of theair. The pipe G is provided with apertures gg, for the admission of air,and one or more of these apertures may be closed when its desired torestrict the admissionof' air.Y J' is a steam pipe, whose nozzle Kdischarges stea'u into the chimney L, and by increasing thedraughtvcauses a partial vacuum in the furnace, so as to facilitate theascent of air, or air and steam combined, thronghthe body of the oil,either in conjunction with a blower, or without any outward pressureexcept that of the atmosphere. M is a blower, having a pipe, N, and anozzle, O, discharging air into the chamber H, and through the body ofthe oil in the receptacle C.` The pipe N`1nay be furnished with acheck-valve to prevent the backward flow of oil when the blast of air isnot on.` P'is an elevated tank or cistern, from which the petroleum orother oil flows into the receptacle C through the pipe R, and thesupplyl of oil isrcgulated by the cock S.

The vtemperature of the air introduced for the above purpose should besuch as to most readily effect the desired results, and will vary withoils of different compositions and specific gravities.

The perforated floor may be replaced by a perforated coil or worm, andthe boiler by an oven, or by aroomwarming pipe, or chest, or otheiwisc.v

If the o'il be violently agitated by mechanical stirring or otherwise,so as to create aspra-y above its surface, an air pipe may' be sointroduced as to bring air into Contact with such spray, and thusproduce that union of air'with the fine particles of oil which ischaracteristic of our method of facilitating combustion.

We claim herein as new, and of our invention- 'Ihe arrangement of areceptacle, C, for hydrocarbon or other oils, or other liquid fuel belowa furnace or combustion-chamber, B, in connection with a pipe or pipes,through which air or air and steam are forced through apertures ornozzles situated below the surface of the liquid fuel, and thencethrough the body of the liquid fuel, substantially as and for thepurpose set forth.

In testimony of which inventionwe hereunto set our hands.
